MECHANISM FOR USE IN PROCESS OF TREATING YARN 7 BY mw QM V ,m'romm's.

Patented May 12, 1931 UNITED STATES PATENT OFFICE WALTER C. VOLK, OF ROME, NEW YORK, ASSIGNOR TO SKENANDOA RAYON CORPORA- TION, OF UTICA, NEW YORK, A CORPORATION OF NEW YORK MECHANISM FOR USE IN PROCESS OF TREATING YARN Application fileii April 15,

This invention relates to a new and improved mechanism to be used in the process of treating yarn. thread and the like, and more particularly in the treatment of such 5 material as rayon. silk, cotton, and so forth. in the method of processing yarn or thread such as rayon, it-has hitherto been the custom to wind the yarn from cakes or spools into skeins and then separate and secure each of said skeins into sections to'prevent raveling or unwinding, after which they are placed upon rolls or carriers and placed on racks or the like for processin It has then been necessary after the processing treati l mcnts have been completed to untie the skeins of yarn and rewind upon cones, spools or bobbins, preparatory to weaving in to clotl 1.

During this method of processing, it Is evident that the yarn or thread has been handled many times and has been mutilated or damaged to a greater or less degree.

The main object of my invention, theretore, is to produce a mechanism whereby the yarn or thread may be wound from a cake,

tormed in the usualwell-lmown manner or directly from the setting bath upon spools or bobbins which may be of novel construction, and then be placed in said mechanism and the further processing be completed, or

again necessary totouch the yarn with the hand or to remove. the. yarn from the bobbin for any reason, thereby producing a much more perfect yarn or thread, substantially eliminating degrading.

Other objects and advantages relating to the detail of construction will more fully appear from the following description taken in connection with the accompanying drawings, in which Figure 1 is a top'plan of a portion of a yarn processing system with the bobbin carriage shown in operative position over one of the vats.

Figure 2 is a side elevation of the device as shown in Figure 1.

section taken inthe plane of the line 4-4, Figure 1.

Figure 5 is an enlarged detail section of one of the bobbins and the supporting means therefor, taken in the plane of line 5-5, Figure 4. i

In the drawings, there is illustrated a portion of a yarn or thread-processing system such as may be used more particularly in the processing of rayon, and in this instance, consists of a plurality of substantially rectangular tanks or vats 1, arranged longitudinally'end to end and supported upon horizontal cross pieces 2 of a plurality of frame members 3.

The end walls of the respective vats l may be formed with less vertical height than'the side walls thereof, thereby positioning the top edges of said end walls in a horizontal plane some distance below the upper edges ofthe side walls. The vats may be tied or secured together by rubber covered inverted U- shaped strips 1 dis osed horizontally over the adjacent end Wal s of any two adjacent vats, said strips being of substantially the same length as the inside width of the vats so as to completely cover the space between any two respective vats to prevent fluid or any foreign substance from collecting therebetween.

.llach of the frames 3 may, as shown, consist of two spaced vertical side leg portions 4, which may be supported upon suitable foundation at their base, and be connected together by a plurality, in this case two, horizontal cross members 2 and 2'. The cross member is located near the feet of the respective upright or leg portions 4, while the member 2 is located some distance below the top of the respective leg portions. The individual frame pieces 3 are arranged transversely the row of wits with one leg on either side thereoi and positioned at the ends or the j nuction of adjacent vats in such a manner that the bottom of the adjacent vats will be supported by the respective common cross members 2 of the frame 8.

The upper ends of the leg portions 4 of the frame piece 3 are tied together by means of a pair of spaced horizontally disposed track rails 5, which may extend the full length of the system and be secured to the upper ends of the respective legs 4 in any suitable manner.

The tracks 5 are also adapted to support one or more bobbin carriages 6, which are adapted to be moved along said tracks to bring the bobbin head support 8 in successive re istration with a plurality of cooperating flixid supply control pipes 7, positioned in the bottom of each of said vats, which will be hereinafter more fully described. Each of the bobbin carriages 6 may, as shown, consist of a substantially vertically disposed rectangular hollow, or chambered head 8, which is composed of two similar sections or halves 9, having their inner adjacent surfaces concaved so as to form a common enclosed chamber 8 when the sections are clamped together. The sections 9 may, as

shown, be secured together by means of bolts or screws 10, which pass through corresponding spaced registering holes provided in lateral outwardly extending flanges 11 constructed about the adjacent edges of said sections.

Each section 9 is also provided with outwardly extending horizontal arms 12, one located at either end thereof, said arms being provided with a groove or slot 13 on the underside thereof adapted to receive one of a pair of supporting shafts 14-, which are in this instance, substantially square in cross section and extend an equal distance in either direction at right angles from the longitudinal center line of said head, and when in operative position extend transversely across and in a plane a short distance above the top of the vats 1, and terminating at either end thereof in a reduced cylindrical portion 15 in a planevabove the track 5 and adapted to have a wheel 16 rotatably mounted thereon in operative alinement with the adjacent track 5.

It is preferable to have the peripheral face of each of said wheels provided with an annular channel or groove thus forming side flanges to better guide the wheels and bobbin carriage as it is moved along the track The horizontal arms or flanges 12 may be secured to the sup-porting shaft 14 in a suitable manner, as by screws or bolts 12.

The supporting shafts 14 are preferably covered with a comparatively thin layer of rubber or composition of material which resists the action of any alkali or acid which may be used in the method of processing. As a matter of fact, it is preferable for all metal parts which come into direct contact with the fluid used to be coated with a thin layer of rubber or its equivalent'so as to prevent corroding of said metals and the contamination of the liquid used, and I have so illustrated the different parts in the accompanying drawings.

The bobbin carriage head 8 is provided with a plurality of, in this instance, eighteen annular bobbin supporting flanges or bosses 17 located in sets of nine, one on each outer vertical surface thereof, each set being arranged in staggered relation in two parallel horizontal rows one above the other.

Each of the said flanges is provided with an annular recess 18 in which is positioned a relatively flexible packing member 19 of sufficient diameter to completely cover the adjacent end of the bobbin 20 when said bobbin is clamped in position on' the bobbin carrier head 8. a

The bobbins 20, may, as shown, be tubular in form with one or both ends open and are each supported in their 'operative position, relative to the bobbin head 8 by means of, in this instance two, bobbin supporting pins 21 arranged in spaced relation above the center of their respective bobbin registering flanges or bosses 17.

The bobbin supporting pins 21 are each provided with a reduced threaded end which is screw-threaded into the head 8 in their respective positions and extend outwardly to a position which will be inside the outer end a of the bobbin 20, when said bobbin is in the operative position on the head 8, it being understood that the horizontal distance between the outside surfaces of any two cooperating pins 21 must be less than the inside diameter of the respective bobbins so that they may both be positioned within said bobbin when the bobbin is in operative position on the head.

The outer ends of the bobbin 520 may, as shown, he closed with a relatively thin cover plate 22, substantially triangular in plane view and of sutiicient size to cover a group of, in this instace three, bobbins at a time as indicated in Figures 2 and 4 for example. and the other figures. The inner surface of said cover plate may be provided with a suitable. packing 23 to prevent leakage between, the cover plate and the. adjacent ends of the cooperating bobbins. Each of the cover plates 22 and the bobbins covered thereby may be clamped in position to the bobbin head 8 by means of a bolt 24, which is secured at one end to the adjacent side of the head member 8 and extending outwardly therefrom, passing through suitable holes located substantially in the center of the respective cover plates and provided with a nut 26, which is adapted to be screwthreaded on the outer end of the bolt 24 thereby clamping the respective bobbins tightly to the head 8 so as to prevent any leakage of liquid at either end, while each of the bobbins 20 is provided with a multiplicity of perforations 27 in the side wall thereof for permitting the passage of fluid from the interior of the bobbin to the thread wound thereon.

lill

' The processing fluid maybe admitted to the interior of each of the bobbins from the common head chamber 8" by means of holes or ports 29 formed in the vertical side walls of the bobbin carrier head 8, said ports 29 being in registration with a lower portion of the interior wall of the bobbin so that all the fluid which may be in the interior chamber of the bobbin at the time the supply is discontinued and the inlet port 30 to the head chamber is opened, will have free passage from the interior of the bobbin out through the head chamber 8, thereby quickly and completely draining the interior of the bobbin, and preventing a greater quantity of liquid from passing through the thread or yarn positioned on the lower portion of the bobbin than passes through the remaining portion thereof.

The inlet port 30 of the chamber 8' is formed in a tubular projection 31 extendin downwardly from the lower edge of the hea sections 9 preferably midway between the ends of the chamber 8' and terminating-in an enlarged annular flange 32, adapted to support a packing ring 33.

The inlet port 30 is adapted to be brought into re istration with any one of a plurallty of flui -supp1y pipes 35, eaeh of which may, as shown, extend upwardly through the bottom of respective vats 1 at or near the center thereof, by movin the carriage 6 along the tracks 5. The fluid-supply pipe consists of a tubular vertically disposed pipe completely covered with rubber inside and out and having its upper end terminating in a plane a short distance below the flange 32 of the inlet port 30 while the lower end thereof extends some distance below the bottom of the respective vat 1 and terminates in an outwardly extending flange portion 36, which is secured to the upper end of a vertically disposed flanged T 37 by bolts or screws 38.

The inlet port 30 may be operatively connected with the particular fluid supply pipe 35 with which it may be in registration by means of the hereinhetore mentioned fluid supply control pipe 7 which is preferably a comparatively long tubular vertically disposed pipe completely covered with rubber and slidablyimounted upon the supply pipe 35 with the upper end thereof normally positioned a short distance above the upper end of said supply pipe while the lower end terminates in an enlarged cylindrical portion 34, positioned between the bottom of the respective vat 1 and the lower flanged end 36 of the supply pipe 35. A cylindrical portion 34 may also be provided at its lower edge with an outwardly extending flange portion 34'.

The T 37, in this instance, has the opposite longitudinal opening to the one registerlng with the supply pipe 35 closed by a gasket or cover 39. The fluid supply pipe 35, together with the T 37 may be supported in their upright position in any suitable manner as by the bracket or stand 40 in alinement with an annular hole 41 provided in the bottom of each of the vats 1. located preferablyat its center in which said supply or control pipes are slidably mounted.

An annular flange casing 42 is secured to the bottom of each of the vats 1 in registration with the respective hole 41 and is adapted to cooperate with a packing nut 43, which is adjustably clamped to the member 42 by screws or bolts 44 to form a liquid tight joint between the liquid supply control pipe 7 and bottom of the respective vat 1.

Another packing nut 45 which is mounted on the supply pipe 35 is :uljustably clamped to the flange 34. by screws or bolts 46 and cooperates with the enlarged portion 34 of the control pipe 7 to form a liquid tight joint between the liquid supply pipe 35 and the fluid control pipe 7.

A flange mel-uber 48 which, in this instance. consists of a flange T similar to the T 37 is disposed in a vertical position and is secured to the T '37 by bolts 49 with the side opening thereof in registration with the side opening of the T 37. The lower end of the valve T 48 may, as shown, be connected by an elbow 50 to a liquid supply pipe 51 leading from a suitable source of supply such as a tank, not shown, adapted to contain processing fluid.

A valve piston 53 provided with a vertical upwardly extending valve stem 54 is slidably mounted in the vertical chamber of the valve member 48 and is adapted to be moved therein to close and 0 en the side outlet opening 55 of said valve y means of a valve operating lever 56 rotatabl connected at one end to a pin 57, secure in the upper portion of a bracket 57, and connected to the valve stem 54 by means of a bifurcated member 58, which is connected at its lower end to said valve stem and slidably connected to the lever 56 by a pin 59 secured to the upper ends of the member 58 and passing through an elongated registering hole provided in the valve operative lever.

An annular flangemember 60 which is socured to the upper end of the valve 48 with bolts 61 is provided with a packing nut 62 adjustably clamped thereto by bolts 63 and with which it cooperates to form. a liquid tight joint around the valve stem 54, which is slidably mounted. in a hole provided in the center of said packing nut.

The valve operating lever 56 is formed at or near its pivotal end with a pair of spaced arms 65, adapted to engage opposite sides of the enlarged portion 34 of the control pipe 7 and pivotally connected thereto by means of outwardly extending lugs or pins 66 secured to or integral with the enlarged portion 34 of the control pipe 7, said pins passing Ill through suitable holes provided in the adjacent portions of the arms 65.

The brackets 57 are located on the opposite side of the supply pipes 35 from that at which the valves 48 are located and may be supported in the operative position in relation to the respective supply pipes by a horizontally disposed bar 67 which in turn is secured to and supported by the lower cross arm 2' of the frame member 3.

The valve lever 56 may be held in its set position by means of a slightly curved pawl 69 pivotally connected at 7 tofsaid valve lever, and having its outer edge serrated to cooperate with the upper beveled edge of a horizontal bar 71, which is in a plane below the lever 56 and secured at its ends to the adjacent vertical members 4 of the respective frame 3.

A positioning locking device for the bobbin carriage 6 is also provided to hold said carriage in cooperative alinement with the fluid supply means, which is provided for each of the vats 1. The locking device may consist of a locking lever 74 secured at one end to a horizontal rock shaft 75 journaled in bearings 7 6 positioned near the outer end of said rock shaft, and secured to the underside of the adjacent rail 5, positioned 011 that side of the vats l, at which the levers 56 are located. The outer end of the lever 74 is provided with a pair of spaced inwardly projecting arms 77 adapted to engage opposite sides of the inner flange of one of the wheels 16 of the carriage 6 when moved into the locking positions with said carriage wheel, when the carriage 6 is in cooperative alinement with the respective fluid supply pipe 35.

The locking lever 74- may, as shown, be moved into and out of locking engagement with the carriage wheel 16 by means of a rock arm 78 secured at one end to the rock shaft 75 in vertical alinement with the valve operating lever 56 while the other end is pivotally connected by a pin to the upper end of a vertically disposed connecting link 80, which has its lower end pivotally connected at 81 to the valve control lever 56.

The upper end of the connecting length 80 is provided with an elongated slot 83 through which the pin 79 passes to permit any further upward movement of the link 80 and lever 56 which may be necessary to bring the fluid control pipe 7 into operative engagement with the inlet port 32 of the head 8 after the locking arm 74 has reached the limit of its locking movement. The pin 7 9 may be yieldingly held in its normal position against the. upper end of the slot 82 by the spring 83 which is coiled about the upper end of the link 80 and positioned between the outer end of the rock arm 78 and a flange or washer 84 secured to the link 80 a short distance below the upper end thereof.

In the processing of thread or yarn such as rayon, it is necessary that the yarn be brought into contact with and be acted upon by a number of different fluids, as, for instance, the thread or yarn may be first washed by water after which it istreated by a desulphurizing agent such, as, for instance, sodium sulphide. After that it may be treated with a bleaching agent, as for instance, chlorine and so on.

With this method in mind it may now be clearly understood that with the bobbin carriage positioned as in Figure 1 with the inlet port thereof in registration with the liquid supply pipe as indicated in Figure 3 and with the inlet pipe 51 connected with a source of processing fluid under pressure, and the valve 48 in the opened position, the fluid will flow through the valve 48, and the supply pipe 35 into the head chamber 8, and then through ports 29 to the interior of the respective bobbins 20, from which osition it will be forced out through the pertorations 27 provided in the wall of the bobbins and through the yarn or thread wound thereon.

This processing may continue until the yarn is thoroughly treated by the desired fluid. whereupon the supply may be cut oil by closing the valve 48, which is accomplished by the operator after first releasing the pawl 69 from the bar 71, moving the valve control bar 56 downwardly, which action will force the valve piston 53 downwardly past the opening 55, thereby closing the same and cutting ofl the flow of liquid to the supply pipe 35. At the same time the liquid supply pipe 7 will be drawn downwardly by the action of the lever 56 upon the pins66, thereby bringing the upper end of said supply control pipe to a plane below the flange 32 of the inlet port 30, where it will be out of the path of movement of the bobbin carriage 6.

This movement of the liquid supply pipe 7 also disconnects the inlet port 30 from the supply pipe 35 and permits any liquid which may be within the bobbins 27 and the head chamber 28 to flow freely out of the inlct port 30 into the interior of the vat l where it may pass through an outlet opening 8.? provided near one end of the bottom of said vat and may be connected in any suitable maner, as by a pipe 86 to a drainage system (not shown).

The downward movement of the valve control lever 56 will also actuate the rock sai't to move the lock arm 74 from locking engagement with the respective wheel 16 of the carriage 6, thereby leaving said carriage free to be moved to the operating position over the supply pipe of the next succeeding vat where it may be connected to the respective fluid supply pipe of said vat by the operator moving the valve lever 56 upwardly, which movement will bring the liquid supply control pipe into engagement with the packing 33 of the flange 32, thus connecting the ltltl llo fluid supply pipe 35 with the inlet port 30 of the head chamber 8'. and at the same time the carriage will be locked in its operative osition by the locking arm .74- coming into ocking engagement with one of the carriage wheels 16, and at the same time the piston 53 will be moved upwardly, thereby opening the port 55 and connecting the bobbin head with any liquid supply to which the inlet pipe 51 or the valve d8 may be connected, as for instance, to a vat or container for a (lo-sulphurizing agent such as sodium sulphide, where upon the yarn will be subjected to this treatment. I

This cycle of processing may continue until the yarn or thread is thoroughly processed by any desired fluid or fluids.

There is also shown a second outlet 87 which may be rovided in the bottom of the vats 1, said out et being connected by an outlet pipe 88 and control valve 89 to a pump or other suitable device (not shown) to return the liquid from the respective vat 1 to the supply chamber for that vat so that by closing the valve 90 which may .be provided in the outlet pipe 86 and opening the valve 89, the flrid may be directed to the source of supply from the respective vat, or by closing the valve 89 and opening the valve 90, the liquid maybe discharged from the respective vat 1 into a drainage system (not shown).

In Figure 3 there is shown an auxiliary means for supplying fluid to the outer portions of the thread or yarn wound upon the bobbins 20 in case said portions do not receive enough of the liquid from the interior of the bobbin to give said portions of the yarn or thread the same degree of treatment as the remaining portion receives.

It consists of a pair of rectangular vats 92 which are positioned one on either side of the bobbin head 8 in close proximity to the upper row of bobbins, and may be supported in any suit this manner as by brackets 93 having one end thereof secured to the vats 92 and the other end secured to cross-pieces or beams 94-secured to or comprising the ceiling of the room in which the apparatus may be located.

The bottoms of the vats 92 are provided with a series of apertures 95 positioned over the outer portions of the thread so that any fluid which may be in the vats will be sprayed or sprinkled over said end portions as it passes through said a ertures 95 from the respective vats 92. Tie fluid may be supplied at will to the respectwe vats by means of a fluid supply pipe 96 connected to an suitable source of supply and provided wit 1 outlet pipes 97 each in cooperative relation with the respective vats 92.

The out let pipes 97 may each be provided with a control valve 98 so that the operator ma control the supply of liquid at will.
